Objectives of the study were to determine the success, complication and recurrence rate of endoscopic papillectomies in familial adenomatous polyposis (FAP) patients. Ampullary adenoma is frequent in familial adenomatous polyposis (FAP) patients. Endoscopic papillectomy is technically demanding for laterally spreading ampullary adenomas and bleeding, perforation and pancreatitis represent typical complications. 40 FAP patients...
Genetic testing and surveillance in infantile myofibromatosis: a report from the SIOPE Host Genome Working GroupNARA Subscribed
Infantile myofibromatosis (IM), which is typically diagnosed in young children, comprises a wide clinical spectrum ranging from inconspicuous solitary soft tissue nodules to multiple disseminated tumors resulting in life-threatening complications. Familial IM follows an autosomal dominant mode of inheritance and is linked to PDGFRB germline variants. Somatic PDGFRB variants were also detected in solitary and multifocal IM lesi...

The carrot psyllid Trioza apicalis Förster 1848 is a carrot pest in Europe that can cause serious damages in case of massive occurrence. Damages up to a total loss of yield have been reported from Scandinavian countries but also from Switzerland. The action threshold to control the pest with chemical pesticides is 0.2 T. apicalis per day and trap caught by sticky traps. We investigated the number of T. apicalis with sticky tra...
Iron cycling in Arctic methane seepsNARA Subscribed
Anoxic marine sediments contribute a significant amount of dissolved iron (Fe 2+ ) to the ocean which is crucial for the global carbon cycle. Here, we investigate iron cycling in four Arctic cold seeps where sediments are anoxic and sulfidic due to the high rates of methane-fueled sulfate reduction. We estimated Fe 2+ diffusive fluxes towards the oxic sediment layer to be in the range of 0.8 to 138.7 μmole/m 2 /day and Fe 2+ f...
Deep phylogeographic structure may indicate cryptic species within the Sparid genus SpondyliosomaNARA Subscribed
Two geographically nonoverlapping species are currently described within the sparid genus Spondyliosoma : Spondyliosoma cantharus (Black Seabream) occurring across Mediterranean and eastern Atlantic waters from NW Europe to Angola and S. emarginatum (Steentjie) considered endemic to southern Africa. To address prominent knowledge gaps this study investigated range‐wide phylogeographic structure across both species. Mitochondri...
The genus Diplodus presents multiple cases of taxonomic conjecture. Among these the D. cervinus complex was previously described as comprising three subspecies that are now regarded as separate species: Diplodus cervinus , Diplodus hottentotus and Diplodus omanensis . Diplodus hottentotus exhibits a clear break in its distribution around the Benguela Current system, prompting speculation that Angolan and South African populati...

Active sulfur cycling by diverse mesophilic and thermophilic microorganisms in terrestrial mud volcanoes of A zerbaijanNARA Subscribed
Summary Terrestrial mud volcanoes ( TMVs ) represent geochemically diverse habitats with varying sulfur sources and yet sulfur cycling in these environments remains largely unexplored. Here we characterized the sulfur‐metabolizing microorganisms and activity in four TMVs in A zerbaijan. A combination of geochemical analyses, biological rate measurements and molecular diversity surveys (targeting metabolic genes apr A and dsr A...
